BUSY (Pin 29): Busy Output. A low-to-high transition oc-
curs when a conversion is started. It stays high until the
conversion is complete. The falling edge of BUSY can be
used as the data-ready clock signal.
RD (Pin 30): Read Data Input. When CS and RD are both
low, the parallel and serial output bus is enabled.
CS (Pin 31): Chip Select. When CS and RD are both low,
the parallel and serial output bus is enabled. CS is also
used to gate the external shift clock.
RESET (Pin 32): Reset Input. When high the LTC2393-16
is reset, and if this occurs during a conversion, the con-
version is halted and the data bus is put into Hi-Z mode.
PD (Pin 33): Power-Down Input. When high, the
LTC2393-16 is powered down and subsequent conversion
requests are ignored. Before entering power shutdown,
the digital output data should be read.
CNVST (Pin 34): Conversion Start Input. A falling edge
on CNVST puts the internal sample-and-hold into the hold
mode and starts a conversion. CNVST is independent of CS.
VCM (Pin 36): Common Mode Analog Output. Typically
the output voltage is 2.048V. Bypass to GND with a 10μF
capacitor.
REFOUT (Pin 37): Internal Reference Output. Nominal
output voltage is 4.096V. Connect this pin to REFIN if us-
ing the internal reference. If an external reference is used
connect REFOUT to ground.
REFIN (Pin 38): Reference Input. An external reference
can be applied to REFIN if a more accurate reference is
required. If an external reference is used tie REFOUT to
ground.
REFSENSE (Pin 39): Reference Input Sense. Leave
REFSENSE open when using the internal reference. If
an external reference is used connect REFSENSE to the
ground pin of the external reference.
IN–, IN+ (Pin 42, Pin 43):
Differential Analog Inputs.
IN+ – (IN–) can range up to ±VREF.
